To all 'whom it may concern:

Be it known that I, Gnovnn C. LLisoN,

a 'citizen of the United States, residing at Louisville, in the county of Stark and. l State of 0hio, have invented a new and useful Vehicle-Tire,- of which the following is a specification. A

My invention relates to improvements 1n vehicle tires comprising two members, one a non-resilient, permanent member and the second a resilient, removable member.-

The objects of my invention are to generally improve devices of the character men-` tioned and to provide a simple and eiiicient vehicle tire adapted for practical use under `varying road conditions. These objects, to-

` gether with other objects apparent to those skilled in the art may be attained by the construction illustrated in the accompanying drawing, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.l i

In the drawing Figure 1 is a transverse 25 sectional view through a vehicle tire em-.

bodying my invention arranged upon a felly, said view being taken on the' line 1-1 of Fig. 4. Fig. 2 is a similar view of the non-resilient member and felly. Fig. 3 is a similar view of the resilient member only. Fig. 4 is a sectional View on the line 4.4. of rig. 1. y

Throughout the several views similar reference numerals indicate similar parts.

The non-resilient member 1 is preferably formed of metal and consists of a hoop adapted to be applied to the periphery of the folly of a wheel somewhat after the man-- ner of the well-known steel tires commonly in'use. r1`he construction of the non-resilient member is well illustrated in Fig. 2

where it will be noted that the flat or base side 2 of the felly attaching portion of the member is adapted'to be applied to the periphery of the felly 3.

The member 1 is provided with the rounding, lateral projection 4 extending beyond the planes of the sides of the felly 3. Formed integrally with the felly attaching portion the substantially semi-circular, radially projecting resilientmember-supp()rting portion 5 is provided, the curved outer face of which at each side joins the fellyattaching portion substantially in the plane of the side of the felly 3, thus producing an oset with the projection 4 at 6 on each lends shown abutting at'lG in Fig. 4.

-as a tire.

- side. Extending into the body of the member 1 and preferably to a point more nearly adjacent the felly 3 than the ofsets at 6 is the outwardly open, annular slot 7, preferably vwith substantially parallel side walls,

'arranged at substantially right angles to the bottom of said slot.

The resilient member illustrated in crossv section in Fig. 3 is preferably composed of rubber and formed with a body portion 8, the periphery of which constitutes the tread surface 9. Formed integrally with the portion 8 are the inwardly extended side flanges-10 adapted tov overlie the portions 5 of the non-resilient member, the extreme inner edges of said flanges fitting against the ofi'- sets atV 6. Also formedintegrally with the portion 8 is the inwardly extended attaching portion 11 constituting an inwardly disposed annular member adapted to lit into the slot 7 of the non-resilient member. In the body of the portion 11 an annular retaining wire 12 is. provided having the oppositely threaded ends 18 adapted to be connected by' a single turnbuckle 14. Said turnbuckle is provided intermediate its ends with transverse apertures 15, said apertures being 'adapted to receive the point of an instrument or tool for turning the turnbuckle as will be well understood by those skilled in the art. rlhe resilient member is not continuous, but is providediwith two At each end the wire receiving aperture in the portion 1l is enlarged to receive the turn'- buekle, and in applying the resilient member to the non-resilient member, the ends of the resilient member may be forced apart ,from each other in an annular direction a sufficient distance to permit the turnbuckle 14 to be applied to the ends of the wire 12. After the wire has been drawn up taut by the turnbuckle the ends of the resilient member may be crowded annularly along the non-resilient member until said ends abut as shown in Fig. 4 in accordance with the lnethod commonly employed in the application of analogous vehicle tires.

One of the principal objects of the present invention is to provide for the ready removal of the resilient member, leaving a non-resilient member capable of practical use by itself As is well understood in the winter and spring when `rural roads are in vrough condition it is not only unnecessary to employ aresilienttire but it is also very injurious to said tire if it is used. With the present invention the resilient member may be readily removed with the aid of few and. simple tools whereupon the Vehicle may run upon the non-resilient member. When it is again desired to apply the resilient member it is only necessary to remove the dirt or mud from lthe slot 10 and to clean the peripheral surfaces of the portions 5 whereupon the resilient member may be applied with the same few and simple ,tools mentioned, and the vehicle will be in condition for use as a resilient-tired vehicle.

With vehiclev tires heretofore commonly in use it has usually been necessary to secure Dthe services of a skilled workman having special tools and devices to accomplish the application of. the resilient tire .to the rim of the v`vlieel,.thev` wires .of such. tires in many ycases being heldby specialclamping and tightening devices until brazed together.

This necessitates annoyance and expensev which the present invention will avoid. l Attention should also'be called to the fact that with tires heretofore commonly in use, when the resilientmember is remevui,l either" in'- tent-ionally or by accident, the fim, usuall of channel shape, is injured by contact wit stone and the like,vwhereas in the present in-I vention the non-resilientmember is so conf structed as to be admirabl adapted for use when the resilient member as been removed.

It should be noted thatl the'y depth of thej slot 7 is such as to prevent the accidental displacement of the resilientl membergwhich so:

commonly causes trouble and inconvenience'A with vehicle tires heretofore 1n use, while said slot being narrow as compared `with the totbal width of the non-resilient member,xa su member will be presented as a tread Witnesses: stantial surface of said non-resilient surface when the resilient member has been removed.

l claim Fora vehicle wheel provided with a felly, a tire, comprising a non-resilient member and a resilient member; said non-resilient member comprising a telly attaching portion adapted to be applied tothe periphery of the felly, integral, lateral, rounding projections extending beyond the planes of the sides of said felly, and an integral resilient-` member-support-ing portion, substantially semi-circular in cross-section and havin-g its curved outer face at each side joined to said felly attachingportion substantially in the planes of the sides of-said elly, producing off-sets with said lateral .project-ions, said resilient-membersupporting portion ro vided with a parallel walled slot extending into the body of the non-resilient member to a point more nearly adjacent said felly than the said off-sets; and a resilient member comprising a body portion havfing' an outer curved tread surface, integral, inwardly extended side flanges having their inner sides adapted to iit the curved outer face of said projecting resilient-member-supporting por-y tion, the extreme edges of said flanges adapted to fit against said off-sets, and an integral, inwardly extended attaching portion adapted to fit into the said slotof the non-resilient member and 'a retaining Wire arranged in said attaching portion for retaining saidl atf taching portion within said slot. v

In testimony that I claim the above,- I have hereunto subscribed my name in the presence of two witnesses.
